Description
Technical Field
The invention relates to an intelligent supervision system, in particular to an intelligent supervision system and method for a mobile communication indoor distribution line.
Background
Currently, mobile communication starts to develop from the 2G age, and has undergone the 2.5G and 3G ages until now, and has rapidly developed into the 4G network age. In accordance with this, the network construction scale of mobile communication is also expanding, and the network coverage is becoming perfect. On this basis, indoor coverage has become an important point for network coverage in the future.
Indoor distribution systems of mobile communication are becoming perfect and have been put into operation and constructed for many years; the number of indoor distributed coverage net points of mobile communication is extremely large, and the distribution area is related to a wide area and scattered; in order to ensure the signal coverage quality of mobile communication, mobile communication operators need to invest huge manpower, material resources and financial resources each year to patrol, maintain and manage an indoor distribution system.
However, for a long time, for a plurality of passive devices such as indoor distributed antennas, radio frequency communication cables, couplers and power splitters in an indoor distributed system, operators lack effective supervision methods and means for the passive devices; once devices in the indoor distribution system are in failure (including short circuit, damage, aging and the like) or lost damage (including theft, owner decoration damage, artificial disassembly, device aging damage and the like) and the like, indoor signal coverage of mobile communication is greatly affected, and operators cannot timely find out the failure of the indoor distribution system. When a user complains, the operator dispatches relevant maintenance personnel to enter a fault point for overhauling. This greatly affects the effective coverage of mobile communication signals in the indoor distribution system of the mobile operator.
Moreover, through the construction of the indoor distribution system of the mobile communication for more than twenty years, the mobile communication operator cannot perform effective statistics and management on the assets of all indoor distribution system networks;

In the construction process of indoor division construction, constructors do not construct according to design drawings, the actual construction line is changed privately, operators cannot be reported in time, and quality hidden danger is reserved for indoor distribution systems.
When the indoor distribution system fails, an operator dispatches maintenance personnel to maintain the failure point; for a fault line, an effective overhaul means is lacked, the fault line is inspected by a manual method, time and labor are consumed, and the efficiency is low;
in summary, each communication device and line at the tail end of the mobile communication room subsystem belong to passive devices, and cannot be effectively monitored and managed; in order to effectively monitor the running working state of an indoor distribution line and the transmission quality of communication signals in real time, and rapidly and effectively locate fault points when an indoor distribution system breaks down, and meanwhile, the indoor distribution system can be effectively and accurately counted and managed, so that the method is an urgent problem to be solved by mobile operators.
